Abstract
BACKGROUND: Cutaneous metastasis with gastric cancer (GC) origin is extremely rare and associated with poor prognosis. Nodular type is the most common type, while other forms are extremely rare. CASE SUMMARY: This study describes severe skin redness, swelling, pain, and fever in a 65-year-old man diagnosed with GC, whose left chest wall, left upper limb, and left back were mainly affected. Firstly, the patient was diagnosed with "lymphangitis" and treated to promote lymphatic return. However, the symptoms were constantly deteriorating, and skin thickening and scattered small nodules gradually appeared. Finally, the skin biopsy confirmed cutaneous metastases, and the patient died 7 d later. CONCLUSION: Our case highlights that cutaneous metastasis should be considered when skin lesions appear in patients with GC.
